如何解决此错误（方法未定义类型）？

Question

这是我的班级

public class EventDetail {  
   private String MemberId;
   private String Category;
   private Date Cdate;

public EventDetail(String MemberId, String Category, Date Cdate)
{
    this.MemberId = MemberId;
    this.Category = Category;
    this.Cdate = Cdate;
}
public Date getDate()
{
    return this.Cdate;
}
public void setDate(Date Cdate)
{
    this.Cdate = Cdate;
}

当我用对象事件

调用方法时

<% for (EventDetail event : events) { %>
<span class="r2"><%=event.getDate() %></span>
<span class="r4"><%=event.Category() %></span>

我收到此错误。如何解决此错误，我认为我的类EventDetail没有显示任何错误。

The method getDate() is undefined for the type EventDetail
            %>
             <div class="row">
                <span class="r1"><%= count %></span>
                <span class="r2"><%=event.getDate() %></span>
                 <span class="r2"><%=event.Place() %></span>
                 <span class="r3"><%=event.Title() %></span>
                 <span class="r4"><%=event.Category() %></span>
